Judo only gets good when you get to the dan ranks. It would take a 5th Dan black belt to compete with a BJJ black belt. Judo belts are given out easily you could get a black in a year. so it isnt correct to use a belt by belt comparison for the two two styles. Because it takes 10 years of training to get a BJJ black belt.

This is nonsense I know white belt judokas that are better fighters in Randoori than some black belts ! In Judo its competition results that count for more. Thats not to take away from black belts - they can teach you techniques that are excellant - but they might not have the fitness and speed.
